Varia 515 firmware version since May 2021

How did you get the RTL515 FW3.30?

No I just tried => 3.26

If you leave the Varia connected to your computer while Garmin Express is open, the update should come up for you to download. It only took 5 minutes for the update to show as available. 

Maybe Europe gets the update a little later

3.26 is the latest public release. 

I would like to see the Garmindevice.xml file from the unit that is at 3.30

My Varia 515 is about 2 months old - from the very beginning/purchase Garmin Express showed and still shows that it has the current software version 3.30

Sometimes new devices were delivered from factory with some minor fw changes. Nothing to be worried about. If it would be an important change, there would already been an update for all.

But I don't care about that :)
The Edge 530 I bought about a year ago had firmware 5.20 from the factory - a version that was never released as an update ;-)

I just got a new RTL515 and went to update the FW but it already has 3.30 on it
